I've run into this too. Looking at the code it seems that $selected_app.data_directory is a hash not a string so the call to sub as a method fails (NoMethodError). I've had a quick look with my sample app. but I can't easily see what was meant to be in there, to allow for it to be fixed...

Same issue for me. Using an iPhone 6 with iOS 10.3.3 with Double Helix Jailbreak. I can ssh in with idb, I get the listing of the apps, but once I selected it I get a crash.
